How to automate invoice processing: A step-by-step guide

Manual invoice processing is an ongoing cycle of delays and inefficiencies. One day, you’re tracking down a manager to approve a $500 office supply order. The next, you're correcting a typo in a vendor’s invoice ID while finance questions why payments are late.

If this sounds familiar, you’re not alone. The average finance team spends 6 hours a week on manual tasks—time that could fuel growth strategies. Let’s look at how automated invoice processing transforms this chase into a streamlined accounts payable workflow, from invoice capture to payment.

What is automated invoice processing?

Automated invoice processing (AIP) is the use of software to streamline and optimize how businesses handle their invoices. It streamlines accounts payable by automating manual tasks like data entry, purchase order matching, sending invoices, and approval routing.

This not only accelerates invoice cycles but also reduces errors, enhances cash flow visibility, and strengthens vendor relationships.

How does invoice automation streamline the accounts payable process?

Let’s say your accounts payable team just received 50 invoices. Half are PDFs sent through emails, a few arrived by mail, and one is even handwritten. Now, your team has to manually enter amounts, match invoices to purchase orders, and chase down managers for approvals—all while vendors follow up about payment status.

Ideally, AP teams would focus on strategic financial management—negotiating discounts, optimizing cash flow, and strengthening vendor relationships. Instead, they’re busy fixing typos in spreadsheets and sending email reminders. This is where automated invoice processing steps in.

How the automated invoicing process works

Instead of chasing down approvals and entering data by hand, an automated invoice process follows a structured, streamlined workflow powered by AI, machine learning, and OCR (Optical Character Recognition).

Here’s how the process works to handle repetitive AP tasks, step by step:

1. Invoice capture and data extraction: Incoming invoices are automatically scanned using OCR technology. Key details like vendor name, invoice amount, and due date are extracted and verified against purchase orders.
2. Automated invoice matching: AI matches invoices to POs and receipts using 2-way or 3-way matching. If discrepancies arise, the system flags them for review before approval.
3. Approval routing: Pre-set workflows send invoices to the right approvers automatically. Approvers receive notifications and can approve invoices instantly, reducing bottlenecks.
4. Scheduled payments and processing: Once approved, payments are scheduled automatically based on due dates and preferred payment methods.
5. Tracking and compliance: Every invoicing step is logged automatically, creating a real-time audit trail to ensure compliance and provide full visibility into cash flow.

Instead of copying over information from spreadsheets, your AP team gains real-time cash flow visibility and operational efficiency.

Manual vs. automated invoice processing: A side-by-side comparison

We’ve covered how invoice automation eliminates tedious tasks, but looking at a direct comparison between manual and automated processing highlights just how much more is being optimized. Beyond just reducing errors, automation reshapes the entire accounts payable workflow—accelerating approvals, strengthening financial controls, and making scaling easier.

The table below breaks down the key differences between manual and automated invoice processing:

The impact of automation goes beyond faster processing times by strengthening financial oversight and future-proofing your AP operations. By eliminating bottlenecks, businesses can ensure timely payments, maintain compliance with accurate record-keeping, and seamlessly scale as invoice volumes grow.

How to implement an automated invoice process in 6 steps

Switching to automated invoice processing requires more than just installing software—it starts with identifying inefficiencies and asking the right questions to address them. Is your team spending hours on data entry? Are approvals constantly delayed? Do invoice errors keep popping up? If so, it’s time to rethink your AP workflow.

Here’s how to set up your system for success:

Step 1—Assess your current workflow

What’s slowing down your AP team? Before automating, take a look at your current process. Are invoices piling up in inboxes? Do mismatched POs lead to payment delays?

Review your current invoice processing workflow to identify time-consuming tasks, bottlenecks, and high-error tasks so you know exactly where automation will have the biggest impact.

Step 2—Select the right automation software

Does your software do more than just scan invoices? Not all automation tools are built the same. Look for invoice automation software with features like OCR, error detection, and seamless ERP integration to effortlessly handle multiple invoice types, automate data capture, and flag errors.

Step 3—Customize your workflow for efficiency

Are approvals still causing delays? Set up workflows that align with your business rules. For example, use conditional logic to automatically route invoices above a specific dollar amount to senior approvers or flag discrepancies for immediate review.

By setting up the right triggers, you eliminate back-and-forth and speed up approvals.

Step 4—Integrate with your accounting system

Is your AP software working in sync with your ERP? A disconnected system can create more work. Ensure your automation tool integrates with QuickBooks, NetSuite, or your existing ERP to prevent duplicate data entry and keep financial records accurate in real time.

Step 5—Test, train, and get buy-in

Will your team actually use the new system? Before rolling out the system company-wide, run tests to ensure everything functions as expected. Train your team to use the software effectively, emphasizing how it simplifies their tasks and improves efficiency.

By setting clear expectations of its AP ROI, your team may feel more confident in using the new system.

Step 6—Monitor, optimize, and scale

Are you getting the full value of automation? Once your system is live, track key metrics like processing time, approval speed, and error rates. Regularly tweak workflows, gather feedback, and adjust rules to keep your AP automation running at peak efficiency—even as your business grows.

By following these steps, you’ll cut invoice processing time, eliminate errors, and future-proof your AP operations. No more chasing approvals, just a faster, better way to manage invoices.
